The actor faced a mandatory minimum of four days in jail for the repeat offense, and served his time in a private city jail. He must also install an ignition interlock device on his car that will prevent the engine from starting if alcohol is detected on his breath.

His attorney, Blair Berk, told PEOPLE, "Chris took immediate responsibility for what he did and has used this experience in such a positive way to get help to confront an addiction to alcohol. He deserves enormous credit for stepping up and getting it done."

The American Pie actor was arrested on June 16 after he was spotted weaving on a Los Angeles freeway.
